18 electrons in its outermost shell called pseudo inert gas configuration.

CHXI04:CHEMICAL BONDING AND MOLECULAR STRUCTURE

313489 Statement A :
Atoms can combine either by transfer of valence of electrons from one atom to another or by sharing of valence electrons.
Statement B :
Sharing and transfer of valence electrons is done by atoms to have an octet in their valence shell.
